Regarding the last point, we do not ask for KYC. What is referred to in the terms is the data provided by the users at the time of registration, that is, username and email.
The reality you are right to ask for KYC~XD
Just like with those typical gambling sites at the moment where they can always possibly ask for some KYC if they do find out something wrong into your gambling activity which it is really common.
It is just on how these terms should be applied on the right way.Gambling sites are regulated specially if its licensed then you would really be expecting with these things.
The important thing here is that they dont ask out any verifications just like on a fiat casino did which crypto gambling sites did really have some boost up or popularity because of this.
About that $1,000,000 Jackpot on hitting 777. Do you have any proofs that you do have this kind of amount for some assurance?
